mkgmap now has support for sea polygons. This means that when you view a map generated by it the ocean will actually be blue, as opposed to the same color as the land with a small coastline separating the two which was previously the case.
I've updated my daily map export of Iceland to use this feature. Here's a before & after picture taken using QLandKarte:

Ooooh lovely :)
Thankyou mkgmap!
I'll have to grab the latest mkgmap and use it this evening.
And thanks Ævar Arnfjörð Bjarmason for letting us know about it.
